Well between the two I have played with [a friend and mine], his [earlier run] is a little tougher on the fingers, but it still flips out via the thumb stud; just a more difficult vs mine I guess. Mine has no problem at all. As others have said try adjusting where your holding the knife/how your holding it. I don't really think about it, but after you were talking about I paid a bit of attention [not sure if this will help in this case, but you could always try adjusting the pivot too, which it probably won't lol].
[bear with me] When I use the flipper, most of the time I am in no hurry to quickly open the knife, so I comfortably hold it by placing the middle of my index finger across the flipper [it is also how I push it down + it doesn't hurt your fingers from scraping etc]. And the other 3 fingers lightly rest towards the bottom of the locking side. Such that the middle finger is over the lock stabilizer, and the other 2 below it. This is very similar to how I hold it when using the thumbstud. Its just the index finger is not on the flipper, but barely resting [sometimes even free floating above the lockbar] on the handle. Hopefully this pic illustrates it [it is a picture of the above hold, not when I'm ready to use the thumbstud, its the quickest pic I had at the ready]
Basically when I am opening with the thumbstud, it is similar to the above pics, except, yes the index finger does rest towards the top of the lock bar, but it is just barely touching it. I am keeping the 560 in place with light pressure from my palm at the bottom of the handle, as well as pressing the most of my pinky, much less with next digit and middle finger. [Think of it like a pressure gradient from the pinky upwards if it helps]
The thumbstuds are actually quite easy/comfy for me to use. Pictures of you using it would help facilitate any extra info. It is difficult to see this as being something that is serviceable via warranty. As it was said it really has been beaten around a lot, so much so ZT bent over for us to make the detent lighter lol.

) to the point where I was killing my thumb determined to get the darn thing to fly open, and it was also slightly off center and tough to disengage the frame lock...
